Using "solar tsunamis" to study the solar corona
Department researchers Dr. Meredith Wills-Davey and
Dr. Craig DeForest used
observations of "solar tsunamis" (large, propagating waves in the solar
atmosphere that seem to be associated with coronal mass ejections, or CMEs) to
indirectly investigate the corona. Observational data from
the Transition Region and Coronal Explorer (TRACE) spacecraft were used to
determine crucial properties of the waves as they propagated, which in turn
provided clues about the local structure of the solar atmosphere. The
detailed investigation of these waves may also aid in understanding
the energetics of CMEs.
